    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

What a clever way to do the background. I also like how you used Math.tan to get the trees.

I was hoping for a more interesting vertical path but couldn't find enough bytes.

Thanks - that was left over from a previous optimisation for computing a different Y offset
